Davenport hail storm history
Scott County·NOAA NCEI Storm Events Database·~75-day publication lag
Scott County, where Davenport is located, has recorded 2 hail events of 1 inch or larger over the past 10 years, with 1 of those events reaching the significant damage threshold of 1.5 inches or greater. The largest hail on record for the county occurred on July 11, 2025, when 1.75-inch hail fell—a size capable of functional damage to standard asphalt shingles. This frequency reflects Davenport's position in eastern Iowa, where organized storm systems track from the central Plains.
Hail in the Davenport area peaks during May and June, when mesoscale convective systems and squall lines moving northeast from the central Plains produce widespread hail across the region. April and July represent secondary months of hail risk, and derecho events—fast-moving windstorms with embedded hail—are also common through this corridor during summer months. The most recent significant hail event in Scott County occurred in mid-July, demonstrating that hail risk extends beyond the primary spring and early-summer window.

Scott County's documented hail record includes only 2 events of 1 inch or larger in the past decade, a relatively low count that reflects the sparse frequency of significant hail in this area. NOAA's Storm Events Database relies on trained spotters, emergency managers, and public reports, which means smaller or rural events may be underreported compared to urban hail occurrences. Current-year data is excluded from the annual frequency table until October, when NOAA's Storm Events Database has processed the full hail season accounting for the standard 75-day reporting lag.
